Merging is used to merge two branches and preserve their history. It also makes it easier to undo mistakes.

Rebase

Rebasing can be beneficial in feature branches. Dev --> feature/<feature-name>

Rabase will rewrite commit history so please don't use it on shared branches like dev and main.

Squash

Squash can be used to condense a lot of commits into one. This can be useful if want to merge dev into main and you have 50 commits.
